DESCRIPTION OF THE PREFERRED EMBODIMENTS

The preferred embodiments of the present invention will now be described with reference to the drawing. Identical elements in the various figures are identified with the same reference numerals.

Reference will now be made in detail to each embodiment of the present invention. Such embodiments are provided by way of explanation of the present invention, which is not intended to be limited thereto. In fact, those of ordinary skill in the art may appreciate upon reading the present specification and viewing the present drawing that various modifications and variations can be made thereto.

As used herein, the singular forms “a,” “an,” and “the,” are intended to include the plural forms as well, unless the context clearly indicates otherwise.

The phrase “and/or,” as used herein in the specification and in the claims, should be understood to mean “either or both” of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases. Thus, as a non-limiting example, a reference to “A and/or B”, when used in conjunction with open-ended language such as “comprising” can refer, in one embodiment, to A only (optionally including elements other than B); in another embodiment, to B only (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc.

As used herein in the specification and in the claims, the phrase “at least one,” in reference to a list of one or more elements, should be understood to mean at least one element selected from any one or more of the elements in the list of elements, but not necessarily including at least one of each and every element specifically listed within the list of elements and not excluding any combinations of elements in the list of elements. This definition also allows that elements may optionally be present other than the elements specifically identified within the list of elements to which the phrase “at least one” refers, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, “at least one of A and B” (or, equivalently, “at least one of A or B,” or, equivalently “at least one of A and/or B”) can refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including elements other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other elements); etc.

A wearable device 104 and components of the wearable device 104 are depicted in at least FIG. 1A-FIG. 13 herein. Moreover, FIG. 5-FIG. 9 depict views to assemble at least a portion of the wearable device 104. It should be appreciated that the wearable device 104 may be configured to control various features of computing devices or smart devices connected to the wearable device 104 via a wireless personal area network technology 178 (such as Bluetooth low energy 4.2 standard) (of FIG. 13), where control is performed in response to detecting a gesture from a user 102 (of FIG. 1A and FIG. 12) while the user 102 is wearing the wearable device 104, detecting an input from the user 102 on a portion of the wearable device 104 while the user 102 is wearing the wearable device 104, and/or detecting biometric parameters of the user 102 while the user 102 is wearing the wearable device 104.

The wearable device 104 may be a watch, a bracelet, a wristband, an ankle band, a ring, or a necklace, among other examples not explicitly listed herein. In preferred embodiments, the wearable device 104 may be the ring. In some examples, the wearable device 104 may comprise a mirrored design such that the wearable device 104 may be worn on both the left hand and the right hand of the user 102.

The wearable device 104 includes a body portion. In some examples, the body portion of the wearable device 104 may comprise a cover. In some examples, the cover may comprise a polycarbonate (PC) material and/or a thermoplastic elastomer (TPE) material, among others not explicitly listed herein. The cover of the wearable device 104 may include both a front cover component 110 and a back cover component 116 (of FIG. 2, FIG. 4, FIG. 9, and FIG. 10). The front cover component 110 and the back cover component 116 may be configured to interact with or be affixed to one another to form the cover.

The wearable device 104 may also include a battery 114 (of FIG. 2, FIG. 5, FIG. 6, FIG. 7, and FIG. 13) and a charging port 124 (of FIG. 2, FIG. 4, and FIG. 11) for charging the wearable device 104. In an example, the battery 114 may be a rechargeable battery. In some examples, the battery 114 may be a lithium-ion battery. In additional examples, the battery 114 may be a lithium-ion rechargeable battery with 60 mAh nominal capacity. In additional examples, the charging port 124 is a Universal Serial Bus (USB) port. In other examples, the charging port 124 is a micro-USB port and may be affixed to a rear of an exterior portion of the wearable device 104. A standard USB charger may be affixed to the USB port or the micro-USB port (e.g., the charging port 124). It should be appreciated that in some examples, the battery 114 may be a non-rechargeable battery. In these examples, the charging port 124 is not included as a component of the wearable device 104. Such charging of the smart device 108 may be wired, wireless, or may include contact charging.

In some examples, the body portion of the wearable device 104 may also include a display (not shown). In a first example, the display may be a light-emitting diode (LED) display. In additional examples, the LED display is a 9×5 LED matrix display. The wearable device 104 may also include an adjustable strap 134 (of FIG. 2, FIG. 4, and FIG. 12) affixed to the body portion at at least two locations to form an opening 150 (of FIG. 4). More specifically, and as depicted in at least FIG. 2, FIG. 11, and FIG. 12, the adjustable strap 134 may be woven through or received by an opening 142 and an opening 140 located on the body portion of the wearable device to form the opening 150. In some examples, the adjustable strap 134 may comprise a fabric material. In other examples, the adjustable strap 134 may be affixed together via a fastening mechanism 136 (of FIG. 2 and FIG. 4), such as Velcro, a clasp, a snap, etc.

In a preferred embodiment, the wearable device 104 may include the ring and the body part of the user 102 may include a finger of the user 102. In additional examples, the finger of the user 102 may be an index finger of the user 102. The adjustability of the adjustable strap 134 allows the wearable device 104 to be worn by users having different finger sizes.

The wearable device 104 may also include a main engine board (e.g., a printed circuit board 180) (of FIG. 2, FIG. 5, FIG. 6, FIG. 7, FIG. 8, FIG. 9, and FIG. 13) and a battery support/protection component 122 (of FIG. 2, FIG. 5, FIG. 6, FIG. 7, and FIG. 13). The battery support/protection component 122 may be a single chip lithium-ion battery protection chip. A screw 120 (of FIG. 2 and FIG. 11) may be received by an opening 144 of the cover to affix numerous components of the wearable device 104. The screw 120 may comprise a stainless steel material, however, the material of the screw 120 is not limited to such. It should be appreciated that another means of fixation may replace the screw 120 to achieve the same result.

It should be appreciated that the wearable device 104 may include one or more components. In an example, the wearable device 104 includes a control component 146, a gesture component 148, and/or a sensing component 158, among other components not explicitly listed herein, as depicted in at FIG. 1A. One or more of the control component 136, the gesture component 148, and/or the sensing component 158 may comprise one or more sensors 160 of FIG. 1D affixed to the body portion of the wearable device 104 such that the one or more sensors 160 may assist the control component 136, the gesture component 148, and/or the sensing component 158 of the wearable device 104 in performing various actions. The one or more sensors 160 of FIG. 1D may include pressure sensors 162, motion detection or detecting sensors 164, motion tracking sensors 166, audio sensors 168, force sensitive resistors 170, piezoelectric sensors 172, accelerometers 174, gyroscopes 190, and/or biometric sensors 176, among others not explicitly listed herein.

As described herein, an “accelerometer” (e.g., the accelerometers 174) is a tool that measure proper acceleration. Proper acceleration is the acceleration, or the rate of change of velocity, of a body in its own instantaneous rest frame. Single-axis and multi-axis accelerometers can detect both the magnitude and the direction of the proper acceleration, as a vector quantity, and can be used to sense orientation due to the direction of weight changes, coordinate acceleration, vibration, shock, and falling in a resistive medium (a case in which the proper acceleration changes, increasing from zero).

Micromachined microelectromechanical systems (MEMS) accelerometers are increasingly present in portable electronic devices to detect changes in the positions of these devices. When coupled with microelectronic circuits, MEMS accelerometers/sensors can be used to measure physical parameters, such as acceleration. MEMS sensors measure frequencies down to 0 Hz (static or DC acceleration). Variable capacitive (VC) MEMS accelerometers are lower range, high sensitivity devices used for structural monitoring and constant acceleration measurements. Piezoresistive (PR) MEMS accelerometers are higher range, low sensitivity devices used in shock applications. For additional information on MEMS accelerometers, see, Matej Andrejašic, “MEMS Accelerometers,” Seminar, University of Ljubljana, Faculty for Mathematics and Physics, Department of Physics, March 2008, Pages 1-17, the contents of which are hereby incorporated by reference in its entirety.

As defined herein, a “gyroscope” (e.g., the gyroscopes 190) is a device used for measuring or maintaining orientation and angular velocity. In particular, the gyroscope is a device that measures the angular velocity of a body about a specified axis of rotation. FIG. 1E depicts a schematic diagram of a traditional MEMS vibratory gyroscope designed to measure the angular velocity of the body about the Z-axis of the ground reference frame. The main principle of MEMS gyroscopes is the transfer of energy between two modes of vibration, the drive and the sense modes, through the Coriolis acceleration. Coriolis acceleration is the acceleration due to the rotation of the Earth, experienced by particles moving along the Earth's surface.

For comparison purposes, the accelerometer (e.g., the accelerometers 174) is used to detect the orientation of the wearable device 104, whereas the gyroscope (e.g., the gyroscopes 190) adds an additional dimension to the information supplied by the accelerometer (e.g., the accelerometers 174) by tracking rotation or twist. More specifically, the accelerometer (e.g., the accelerometers 174) measures linear acceleration of movement and the directional movement of the wearable device 104. The accelerometer (e.g., the accelerometers 174) is not able to resolve its lateral orientation or tilt during that movement accurately unless the gyroscope (e.g., the gyroscopes 190) is present to add that information. The gyroscope (e.g., the gyroscopes 190) measures the angular rotational velocity. As such, both sensors measure rate of change.

It should be appreciated that the one or more sensors 160 may be placed on any suitable location on the wearable device 104. In a first example, the one or more of the sensors 160 may be located on or affixed to the body portion of the wearable device 104. In a second example, the one or more sensors 160 are contoured along an inside surface of the body portion of the wearable device 104. In a third example, the one or more sensors 160 may be contoured along an outside surface of the body portion of the wearable device 104. In a fourth example, a subset of the one or more sensors 160 are contoured along the inside surface of the body portion of the wearable device 104 and another subset of the one or more sensors 160 are contoured along the outside surface of the body portion of the wearable device 104. In a fifth example, the one or more sensors 160 may comprise an array of sensors radially distributed around the inner surface or the outer surface of the body portion of the wearable device 104.

In some examples where the wearable device 104 includes the control component 136, the wearable device 104 may include a receiver portion 126 (of FIG. 2, FIG. 3, FIG. 4, FIG. 9, and FIG. 10). As depicted, a shape of the receiver portion 126 is a hexagonal shape. However, the shape of the receiver portion 126 is not limited to such and may alternatively include a circular shape, a crescent shape, a triangular shape, a square shape, a parallelogram shape, a pentagonal shape, an octagonal shape, a rhombus shape, a heptagonal shape, an elliptical shape, or a star shape, among others not explicitly listed herein.

The receiver portion 126 may be located on the cover of the wearable device 104. In some examples, the receiver portion 126 may include a first component 128, a second component 130, and a third component 132 (of FIG. 2 and FIG. 3). Each of the first component 128, the second component 130, and the third component 132 may be buttons or locations on the receiver portion 126 that receive input from the user 102. In additional examples, the first component 128 may be an “up” component and the third component 132 may be a “down” component. The second component 130 may be located between the first component 128 and the third component 132. The second component 130 may be an “advance” or a “rewind” component.

The first component 128, the second component 130, or the third component 132 of the receiver portion 126 may receive the input from the user 102 (such as a push or a press input) to modify a parameter of a smart device 108. As described, the wearable device 104 may be configured to control various features of computing devices or smart devices connected to the wearable device 104 via the wireless personal area network technology 178 (such as Bluetooth low energy 4.2 standard). The smart device 108 may include a smart light, a smart television, a smartphone, a smart thermostat, a smart doorbell, a smart lock, a smart refrigerator, smart glasses, a smart watch, or a smart speaker, among other examples not explicitly listed herein. The parameter may include an on position, an off position, a pause position, a play position, a channel, a volume, a color (e.g., of a light), a song, a movie, a brightness (e.g., of the light), a locked status, an unlocked status, a temperature, presented content, a phone call, a message, a notification, two-dimensional content, and/or three-dimensional content, among other examples not explicitly listed herein.

More specifically, the control component 136 of the wearable device 104 may be configured to receive, from the receiver portion 126, the input from the user 102. In response, the control component 146 may be configured to transmit the input via the wireless personal area network technology 182 to the smart device 108 to modify the parameter of the smart device 108.

In a first illustrative example, the user 102 may wear the wearable device 104 on a left index finger of the user 102 and may execute the action, on the first component 128 of the receiver portion 126 of the wearable device 104, via a left thumb of the user 102 to increase the parameter (e.g., the temperature) of the smart device 108 (e.g., the smart thermostat). In a second illustrative example, the user 102 may wear the wearable device 104 on a right index finger of the user 102 and may execute the action via a right thumb of the user 102 on the third component 132 of the receiver portion 126 of the wearable device 104 to decrease the parameter (e.g., the temperature) of the smart device 108 (e.g., the smart thermostat). In a third example, the user 102 may wear the wearable device 104 on the left index finger of the user 102 and may execute the action via the left thumb of the user 102 on the second component 130 of the receiver portion 126 of the wearable device 104 to advance a slide of a presentation in an application on the smart device 108 (e.g., the smartphone).

In further illustrative examples, the user 102 may execute the action on the receiver portion 126 to turn on or turn off the smart light, increase or decrease a brightness of the smart light, increase or decrease a volume associated with the smart television, change a channel on the smart television, advance a slide or a song in an application executed on the smartphone, increase or decrease a temperature associated with the smart thermostat, answer a phone call or text message on the smartphone, respond to a notification on a social media application executed on a smartphone or a tablet, lock or unlock the smart lock, increase or decrease a volume of the smart speaker, and/or modify two-dimensional content or three-dimensional content on the smart device 108. It should be appreciated that these examples are provided for illustrative purposes only and other examples are contemplated.

In examples where the wearable device 104 is the ring being worn on the index finger of the user 102, the gesture component 148 of the wearable device 104 may allow the user 102 to use his/her fingers to control the smart device 108. The gesture component 148 may interpret signals from the one or more of the sensors (such as the pressure sensors 162) located on or affixed to the wearable device 104 to identify individual actions performed by the user 102. The individual actions performed by the user 102 may include touch gestures and/or non-touch gestures. Examples of the touch gestures may include touching a surface of an object (such as the smart device 108) with the index finger of the user 102 and/or sliding the index finger of the user 102 on the surface of the smart device 108, among others not explicitly listed herein. Examples of non-touch gestures may include the user 102 bending his/her index finger, moving his/her index finger in the air, and/or waving his/her index finger in the air, among others not explicitly listed herein.

The gesture component 148 may detect signals from the one or more sensors 160 to identify an individual action performed by the user 102. The gesture component 148 may then transmit the individual action via the wireless personal area network technology 182 to the smart device 108 to modify the parameter of the smart device 108. As a first illustrative example, the gesture component 148 may detect signals from the one or more sensors 160 to identify the individual action performed by the user 102 (e.g., the non-touch gesture of the user 102 bending his/her index finger while wearing the wearable device 104) and may transmit the individual action via the wireless personal area network technology 182 to the smart device 108 to modify the parameter of the smart device 108 (e.g., decrease the volume associated with the smart television). In a second illustrative example, the gesture component 148 may detect signals from the one or more sensors 160 to identify the individual action performed by the user 102 (e.g., the touch gesture of the user 102 sliding his/her index finger upwards on the surface of the smart device 108, e.g., a tablet) and may transmit the individual action via the wireless personal area network technology 182 to the smart device 108 to modify the parameter of the smart device 108 (e.g., increase the volume associated with the smart television). It should be appreciated that these examples are provided for illustrative purposes only and other examples not explicitly described herein are contemplated.

In additional examples, the individual action performed by the user 102 may be a gesture input action. Such gesture input action may include movement of the finger of the user 102, the hand of the user 102, and/or the arm of the user 102. A non-exhaustive list of gesture input actions includes: a clockwise or a counterclockwise circular gesture input action by the finger of the user 102 (e.g., to turn on a light), a movement of the finger of the user 102 in a triangular motion, a stop gesture input action by the hand of the user 102 (e.g., to pause a song), an “X”-shaped gesture input action by the finger of the user 102, a movement of the finger or the hand of the user 102 in an upwards direction (e.g., to increase a volume of a song or a brightness of a light), a movement of the finger or the hand of the user 102 in a downward direction (e.g., to decrease the volume of the song or the brightness of the light), and/or a flick or swipe of the hand of the user 102 in a leftward direction or a rightward direction (e.g., to move progress of a presentation forward or backward), among others.

The gesture input action from the user 102 is bound to the modification of the parameter of the smart device 108 by means of one or more algorithmic classifiers 192 (as depicted in FIG. 1B and FIG. 1C). In examples, at least one of the one or more algorithmic classifiers 192 comprises a machine learning classifier. The array of algorithms are used to process data (e.g., gesture detection data 196, tap detection data 194, sensor fusion data that determines orientation 198, etc.) from onboard motion sensors (e.g., the accelerometers 174 and the gyroscopes 190). Data processing is performed using proprietary algorithms, e.g., to obtain the orientation of the wearable device 104, to detect finger taps of the user 102 on any surface, and/or to detect energy saving motions by the user 102, among others. These algorithms may be processed either on the wearable device 104 via embedded software (see, FIG. 1B) or on the receiving device (e.g., the smart device 108) (see, FIG. 1C). In some examples, software, configured to interact with the wearable device 104, may be executable on the smart device 108. The software may run on MacOSX, Windows 10, and Linux. Further, a communication layer may be associated with the software.

Furthermore, motion sensor data from the one or more sensors 160 can be processed using machine learning to perform real-time gesture detection. In particular, the motion sensor data from the one or more sensors 160 can be processed using time-series classification to perform the real-time gesture detection. These gestures while wearing the wearable device 104 can be bound to certain actions (e.g., to modify the one or more parameters) on the smart device 108.

As described herein, “machine learning” is a subset of artificial intelligence and is the study of computer algorithms that improve automatically through experience. Machine learning algorithms build a mathematical model based on sample data (or “training data”) in order to make predictions or decisions, without being explicitly programmed to do so.

As defined herein, a “time series data set” is a data set which represents some measurements of a quantity over a time period. The behavior of the series heavily depends on the order of the points. Time series analysis includes developing statistical models to provide reasonable explanations regarding sample data. These models can be developed using various machine learning technologies.

As defined herein, “time series classification” deals with classifying data points over a time period based on its' behavior. Time series classification is a problem in the field of data mining. See, Q. Yang, et al., “10 Challenging Problems in Data Mining Research,” Inf Technol Decis Mak, 2006, 5(4), Pages 597-604, the contents of which are hereby incorporated by reference in its entirety. With the increase of temporal data availability, numerous time series classification algorithms have been proposed. See, D F Silva, et al., “Speeding Up Similarity Search Under Dynamic Time Warping By Pruning Unpromising Alignments,” 2018, Data Min Knowl Discov, 32(4), Pages 988-1016, the contents of which are hereby incorporated by reference in its entirety.

Due to their natural temporal ordering, time series data are present in almost every task that requires some sort of human cognitive process. See, M. Längkvist, et al., “A Review of Unsupervised Feature Learning and Deep Learning For Time-Series Modeling,” Pattern Recognit Lett, 2014,42, Pages 11-24, the contents of which are hereby incorporated by reference in its entirety. Any classification problem using data that is registered taking into account some notion of ordering can be cast as a time series classification problem. Time series are encountered in many real-world applications, such as human activity recognition, acoustic scene classification, cyber-security, and electronic health records. See, H. F. Nweke, et al., “Deep Learning Algorithms for Human Activity Recognition Using Mobile and Wearable Sensor Networks: State of the Art And Research Challenges,” Expert Syst Appl, 2018, 105, Pages 233-261, the contents of which are hereby incorporated by reference in its entirety. Human activity recognition systems are developed as part of a framework to enable continuous monitoring of human behaviors. The extraction of relevant features is the most challenging part of the mobile and wearable sensor-based human activity recognition pipeline. See, H. F. Nweke, et al.

Solutions to the problem of time series classification include use of a nearest neighbor (NN) classifier coupled with a distance function, Dynamic Time Warping (DTW) distance when used with a NN classifier, deep neural networks, pattern extraction, and weighted dynamic time warping, among others. See, A. Bagnall, et al., “The great time series classification bake off: a review and experimental evaluation of recent algorithmic advances,” Data Min Knowl Discov, 2017, 31(3), Pages 606-660; J. Lines, et al., “Time series classification with ensembles of elastic distance measures,” Data Min Knowl Discov, 2015, 29(3), Pages 565-592; Hassan Ismail Fawaz, et al., “Deep Learning for Time Series Classification: a Review,” Data Mining and Knowledge Discovery, 2019, 33, Pages 917-963; Pierre Geurts, “Pattern Extraction for Time Series Classification,” European Conference on Principles of Data Mining and Knowledge Discovery, 2011, Pages 115-127; Young-Seon Jeong, et al., “Weighted Dynamic Time Warping for Time Series Classification,” Pattern Recognition, 2011, 44(9), Pages 2231-2240, the contents of which are hereby incorporated by reference in their entirety.

It should further be appreciated that, in response to receiving the input from the user or in response to recognizing the gesture input by the one or more algorithmic classifiers 192, a haptic response is provided by the wearable device 104 to the user 102. As described herein, “haptic feedback” refers to any technology that can create an experience of touch by applying forces, vibrations, or motions to the user 102. As defined herein, “haptic feedback” refers to the use of touch to communicate with the user 102. As such, the wearable device 104 comprises one or more tactical sensors that measure forces exerted by the user 102 on the interface. Examples of haptic feedback include the vibration of a mobile device or a rumble from a game controller. It should be appreciated that the examples of haptic feedback provided herein are for illustrative purposes only and are not exhaustive.

In additional examples, the sensing component 158 may include the biometric sensors 176. As described herein, each of the biometric sensors 176 refers to a suitable device that can sense a biometric feature of the user 102 while the user 102 is wearing the wearable device 104. In one embodiment, a sensor of the biometric sensors 176 takes the form of a fingerprint sensor that is configured to sense a fingerprint (e.g., when the wearable device 194 is placed over the finger, such as the index finger, of the user 102). Examples of other biometric features that can be sensed by the biometric sensors 176 instead of or in addition to a fingerprint include, but are not limited to, a finger vein, an oxygen saturation level, a pulse, a quantity of calories burned, and a heartbeat pattern. Of course, these are merely examples, and other types of the biometric sensors 176 can be used to sense other types of biometric features.

The biometric sensors 176 may assist the sensing component 158 in detecting pressure imparted by the body part of the user 102 while the user 102 is wearing the wearable device 104. The sensing component 158 may measure one or more parameters (e.g., biometric parameters) of the user 102 and may transmit the one or more biometric parameters via the wireless personal area network technology 182 to the smart device 108. As an illustrative example, the biometric sensors 176 may assist the sensing component 158 in detecting the pressure imparted by the body part of the user 102 (e.g., the index finger of the user 102) while the user 102 is wearing the wearable device 104 (e.g., the ring), measuring the one or more biometric parameters (e.g., a quantity of calories burned during a time period and a pulse of the user 102), and transmitting the one or more biometric parameters of the quantity of calories burned during the time period and the pulse of the user 102 via the wireless personal area network technology 182 to an application executed on the smart device 108 (e.g., the smartphone). The application executed on the smartphone may receive the one or more biometric parameters and may store these biometric parameters. The application executed on the smartphone may also utilize the received one or more biometric parameters for further analysis or other purposes.

It should be appreciated that the one or more sensors 160 described herein are part of a printed circuit board 180 located in the interior of the wearable device 104. In this embodiment, the printed circuit board 180 comprises a controller, non-volatile memory, a wireless chip, an antenna 188, user interface element(s), and the rechargeable battery 114, which are all operatively in communication with one another. The “operatively in communication with” could mean directly in communication with or indirectly (wired or wireless) in communication with through one or more components, which may or may not be shown or described herein. It should be noted that these components are merely examples and fewer or more components can be used.

In general, the non-volatile memory is configured to store information from an authorized user, such as detected user actions, detected or sensed biometric parameters, etc. The non-volatile memory can include any suitable non-volatile storage medium, including NAND flash memory cells and/or NOR flash memory cells. The memory cells can take the form of solid-state (e.g., flash) memory cells and can be one-time programmable, few-time programmable, or many-time programmable. The memory cells can also be single-level cells (SLC), multiple-level cells (MLC), triple-level cells (TLC), or use other memory cell level technologies, now known or later developed. Also, the memory cells can be fabricated in a two-dimensional or three-dimensional fashion.

In some examples, the one or more sensors 160 may detect the input action performed by the user 102, the gesture action performed by the user 102, and/or the biometric parameters of the user 102 and may determine whether the actions or the biometric features detected match actions or biometric features stored in the memory. If there is a match, the controller is configured to enable a function of the wearable device 104. The controller can take the form of processing circuitry, a microprocessor or processor, and a computer-readable medium that stores computer-readable program code (e.g., firmware) executable by the (micro)processor, logic gates, switches, an application specific integrated circuit (ASIC), a programmable logic controller, and an embedded microcontroller, for example. The controller can be configured with hardware and/or firmware to perform the various functions described herein.

As used herein, a “function” of the wearable device 104 can take any suitable form. For example, in some embodiments, the wearable device 104 can have one or more of the following functions: accessing user data stored in a memory of the wearable device 104, opening a door, making a payment, authenticating a secure application in the smart device 108 in communication with the wearable device 104, and controlling an application in or receiving an alert from the smart device 108 in communication with the wearable device 104. In another embodiment, the function is turning the wearable device 104 on or waking the wearable device 104 up from a sleep mode (where some other functions of the wearable device 104 (e.g., a displayed clock) can still be enabled even though others are not). In one embodiment, the function of the wearable device 104 is performed using the wireless chip and/or the antenna 188 (together referred to as a wireless transceiver (e.g., for near field communications (NFC)) to send and receive communications with the wearable device 104. The user interface element(s) can be related or unrelated to the function. For example, in one embodiment, the user interface element is a display device that displays the current time irrespective of whether an authorized user is wearing the wearable device 104. In examples, the display device is a visual display. As another example, the user interface element can be a buzzer/vibrator, LED light, an OLED light, an LCD light, etc. that provides an authorized user with an alert from a paired smart device 108. Since the wearable device 104 enables a function only if the action detected, the gesture detected, or the biometric feature sensed by the one or more sensors 160 matches the biometric feature or the actions stored in the memory, this ensures that functions of the wearable device 104 can be enabled only for its true owner.

The wearable device 104 may store a plurality of actions and/or biometric features of the user 102, where each action or each biometric feature is associated with a different function of the wearable device 104. For example, fingerprints of two or more of the user's fingers can be stored in the wearable device 104 and associated with different functions. That way, a different function can be enabled depending on which finger the user 102 puts the wearable device on. As another alternative, three-dimensional functions can be enabled/disabled based on the direction of movement of the wearable device 104 as sensed by movement across finger segments.

Also, any suitable type of memory can be used. Semiconductor memory devices include volatile memory devices, such as dynamic random access memory (“DRAM”) or static random access memory (“SRAM”) devices, non-volatile memory devices, such as resistive random access memory (“ReRAM”), electrically erasable programmable read only memory (“EEPROM”), flash memory (which can also be considered a subset of EEPROM), ferroelectric random access memory (“FRAM”), and magnetoresistive random access memory (“MRAM”), and other semiconductor elements capable of storing information. Each type of memory device may have different configurations. For example, flash memory devices may be configured in a NAND or a NOR configuration.

The memory devices can be formed from passive and/or active elements, in any combinations. By way of non-limiting example, passive semiconductor memory elements include ReRAM device elements, which in some embodiments include a resistivity switching storage element, such as an anti-fuse, phase change material, etc., and optionally a steering element, such as a diode, etc. Further by way of non-limiting example, active semiconductor memory elements include EEPROM and flash memory device elements, which in some embodiments include elements containing a charge storage region, such as a floating gate, conductive nanoparticles, or a charge storage dielectric material.

Multiple memory elements may be configured so that they are connected in series or so that each element is individually accessible. By way of non-limiting example, flash memory devices in a NAND configuration (NAND memory) typically contain memory elements connected in series. A NAND memory array may be configured so that the array is composed of multiple strings of memory in which a string is composed of multiple memory elements sharing a single bit line and accessed as a group. Alternatively, memory elements may be configured so that each element is individually accessible, e.g., a NOR memory array. NAND and NOR memory configurations are exemplary, and memory elements may be otherwise configured.

The semiconductor memory elements located within and/or over a substrate may be arranged in two or three dimensions, such as a two dimensional memory structure or a three dimensional memory structure. In a two dimensional memory structure, the semiconductor memory elements are arranged in a single plane or a single memory device level. Typically, in a two dimensional memory structure, memory elements are arranged in a plane (e.g., in an x-z direction plane) which extends substantially parallel to a major surface of a substrate that supports the memory elements. The substrate may be a wafer over or in which the layer of the memory elements are formed or it may be a carrier substrate which is attached to the memory elements after they are formed. The substrate may include a semiconductor.

The memory elements may be arranged in the single memory device level in an ordered array, such as in a plurality of rows and/or columns. However, the memory elements may be arrayed in non-regular or non-orthogonal configurations. The memory elements may each have two or more electrodes or contact lines, such as bit lines and word lines.

A three dimensional memory array is arranged so that memory elements occupy multiple planes or multiple memory device levels, thereby forming a structure in three dimensions (e.g., in the x, y and z directions, where the y direction is substantially perpendicular and the x and z directions are substantially parallel to the major surface of the substrate). As a non-limiting example, a three dimensional memory structure may be vertically arranged as a stack of multiple two dimensional memory device levels. As another non-limiting example, a three dimensional memory array may be arranged as multiple vertical columns (e.g., columns extending substantially perpendicular to the major surface of the substrate, i.e., in the y direction) with each column having multiple memory elements in each column. The columns may be arranged in a two dimensional configuration, e.g., in an x-z plane, resulting in a three dimensional arrangement of memory elements with elements on multiple vertically stacked memory planes. Other configurations of memory elements in three dimensions can also constitute a three dimensional memory array.

In a three dimensional NAND memory array, the memory elements may be coupled together to form a NAND string within a single horizontal (e.g., x-z) memory device levels. Alternatively, the memory elements may be coupled together to form a vertical NAND string that traverses across multiple horizontal memory device levels. Other three dimensional configurations can be envisioned wherein some NAND strings contain memory elements in a single memory level while other strings contain memory elements which span through multiple memory levels. Three dimensional memory arrays may also be designed in a NOR configuration and in a ReRAM configuration.

Typically, in a monolithic three dimensional memory array, one or more memory device levels are formed above a single substrate. Optionally, the monolithic three dimensional memory array may also have one or more memory layers at least partially within the single substrate. As an example, the substrate may include a semiconductor. In a monolithic three dimensional array, the layers constituting each memory device level of the array are typically formed on the layers of the underlying memory device levels of the array. However, layers of adjacent memory device levels of a monolithic three dimensional memory array may be shared or have intervening layers between memory device levels.

Two dimensional arrays may be formed separately and then packaged together to form a non-monolithic memory device having multiple layers of memory. For example, non-monolithic stacked memories can be constructed by forming memory levels on separate substrates and then stacking the memory levels atop each other. The substrates may be thinned or removed from the memory device levels before stacking, but as the memory device levels are initially formed over separate substrates, the resulting memory arrays are not monolithic three dimensional memory arrays. Further, multiple two dimensional memory arrays or three dimensional memory arrays (monolithic or non-monolithic) may be formed on separate chips and then packaged together to form a stacked-chip memory device.

Associated circuitry is typically required for operation of the memory elements and for communication with the memory elements. Memory devices may have circuitry used for controlling and driving memory elements to accomplish functions, such as programming and reading. This associated circuitry may be on the same substrate as the memory elements and/or on a separate substrate. For example, a controller for memory read-write operations may be located on a separate controller chip and/or on the same substrate as the memory elements.

In a preferred embodiment and as depicted in at least FIG. 13, the electronics of the wearable device 104 may be assembled on the printed circuit board 180 located in the interior of the wearable device 104 and consisting of baseband hardware and radio frequency electronic circuits. The main control unit of the wearable device 104 is a semiconductor that provides computing, storage, and Bluetooth Low Energy radio services.

The antenna 188 is integrated into the printed circuit board 180. In examples, the antenna 188 is a printed wiring board (PWB) strip line (IFA) antenna 188 with a maximum gain of −5.4 dBi and is implemented in two layers in the printed circuit board 180. The motion tracking device 184 is a 9-Axis Micro-Electro-Mechanical Systems (MEMS). The semi-conductor light source 152 comprises white LED's. In some examples, the semi-conductor light source 152 is an LED matrix display.
